This is a DC sucker - type electromagnet that's a real powerhouse! It has a 15kg holding force and runs on just 2W of power at 5V. You can easily change its magnetic poles by swapping the input power's positive and negative poles. With its compact size, it's perfect for DIY electromagnetic locks, smart storage cabinets, and intelligent doors. The electromagnet consists of a wire coil around an iron core. When current flows through the coil, it creates a magnetic field that magnetizes the iron core, just like a permanent magnet. The core is made of pure iron or silicon steel, which can be quickly magnetized and demagnetized. So, it becomes magnetic when powered on and loses magnetism right after power - down. Note that the 'holding force' of 15kg doesn't mean it can pick up 15kg. Divide this force by 5 - 10 to estimate the pick - up weight, around 3kg max. The pick - up ability depends on a flat surface, maximum surface contact, and the ferromagnetic metal content. A flat steel cube works best, while oddly - shaped or rubber/plastic - covered objects won't work well. The electromagnet can be energized for a long time when attached to an object's surface, but avoid long - term energization when there's nothing to attract. Specification: Rated Voltage is DC 5V, Rated Power is 2W, Holding Force is 15kg, and Wire Length is 28cm. Shipping list includes one 5V Electromagnet (15 Kg Height 25mm) and one Mounting Screw.
Using this electromagnet is easy. First, make sure to connect it to a 5V DC power source. You can change the magnetic poles by switching the positive and negative wires. This electromagnet is great for DIY projects like making electromagnetic locks or smart storage cabinet systems. When it comes to picking up objects, remember that the 15kg holding force doesn't mean it can lift 15kg. Divide the holding force by 5 - 10 to get a rough idea of the weight it can pick up, around 3kg max. For the best results, use flat ferromagnetic objects. Avoid trying to pick up oddly - shaped or rubber/plastic - covered items. When the electromagnet is attracting an object, it can be energized for a long time. But don't keep it powered on for long when there's nothing to attract. To maintain it, keep it clean and dry. Check the wire connections regularly to make sure they're secure. That's it! Enjoy using your new electromagnet.
